V series adopts U-shaped resonant cavity to make it long by folding, which solves the problems that poor quality laser beam casued by optial resonant cavity deformed, output power instability and others.

It makes power density more concentrated and enhances the photoelectric conversion rate that changing the cavity, and extend the lifetime of laser tube.
It can be widely used in industry like sheet metal cutting, die cutting, advertising, furniture and so on.


1. Unique Shape Design
SPT CO2 laser tube have Its unique structure not only maintain the appearance of CO2 laser tube's beauty, but also makes the flexural capacity of the pipe body variant multiplied, so that CO2 laser tube work stability has greatly improved.

2.Significant Cutting Speed
SPT CO2 laser tube using the basement membrane beam quality design, improve product quality, the same power as compared to other products on the market, the SPT CO2 laser tube’s cutting speed apparently higher than other CO2 laser tube.

3. Long Life and High Power
SPT CO2 laser tube have it’s own special patent .it's applications combined with catalytic technology, greatly extending the life and power of the laser tube. Such as the SPT CO2 laser tube 150 w ,it’s max output power can reach about 180 w. other company’s CO2 laser tube merely can beyond us.

4. Light Weight
To compared SPT CO2 laser tube with the same other general Co2 laser tube, Our SPT CO2 laser tube’s weight is lighter than others’. which will help enterprise to have a more diversify application on CO2 laser tube.

5.Long Warranty
SPT laser company believe that :“QUALITY IS OUR CULTURE”.so we always hope to provide our best services to all of our buyers. One of our core advantages is the After-Service, we committed that our SPT CO2 laser tube 150w have 6 months warranty to you.

6. Resonable Price
SPT CO2 laser tube have providing reasonable price for all customers, compared to any other CO2 laser suppliers ,we think our products can give you a total different experience.
SPT CO2 laser tube ,Welcome your inquiry.

CO2 laser (laser tube) Installation instructions

1. Make sure the electrodes are connected correctly;

2. The cooling water pipe installation. When installing water pipe, please make sure the cooling water inlet must follow from the positive to negative, and down into the water, and the interface is not leaking. Before starting the laser tube must store enough water in the water cooling pipes and no air bubbles before use (must check every time before start laser tube). If the laser tube is mounted vertically, please ensure that no air bubbles at the top of the laser tube. It will cause thermal shock when it runs with air bubbles in the water pipe, which is easy to damage your laser tube.

3. To maintain the good performance of laser tube, keep the cooling water temperature between 20-25 °C. The instability of cooling water's temperature will influence laser tube output power.

4. When installing the laser tube, please try to ensure the 1/4 point in laser tube length is on laser tube holder, this can help your laser tube get best working performance. And leave enough space between the laser tube positive end (it has high voltage electricity) and any metal surface of your laser machine. If the space is not big enough, it will cause ignition between high voltage power used to trigger the laser tube and the metal surface of laser machine, and thus lead to laser tube damage and even breakdown of major electronic components on your laser machine.

5. Recommend laser machine consumers to put automatic checkout device into your laser tube water cooling system to prevent laser tube stoppage due to overheating failure caused by lack of water when laser tube is working, please consult your laser machine supplier for details.
